Adenoid Cystic Carcinoma of the Bartholin’s Gland: A Diagnostic Challenge

Adenoid cystic carcinoma (ACC) originating in the Bartholin's gland is a rare entity. We report the case of a female in her 50s who presented with a progressively enlarging right-sided vulvar mass and intermittent pain. Although preoperative biopsy and MRI suggested a benign lesion, postoperative histopathological examination confirmed the diagnosis of ACC. ACC can be challenging to diagnose using MRI, and misidentifying it as a benign lesion can lead to insufficient surgical treatment and a poorer prognosis. Therefore, ACC should be included in the differential diagnosis of vulvar soft-tissue masses when the lesion shows slow, progressive enlargement.
